Questions about Denon HA-500 Head Amp

Post by ChristianLyk » 12 Feb 2019 17:49

Recently i bought an old Denon model HA-500 MC cartridge head amp. I found it hard to find anything about the amp online, so i was not exactly sure what to expect from it, other than knowing it was a nice quality moving coil head amp.
When i hooked the amp to my turntable and amplifier today, and i turned it up to 32 dB, the sound became kind of buried in the gain. I am fairly new to all of this, so i was wondering if anybody owns or knows anything about the Denon HA-500, and can tell about the effects of it. What is it supposed to do?

Regards Christian

Other than that, we'll need to know what you're playing on in order to offer sensible advice. It sounds like you're applying too much gain though.

My turntable is a Philips model AF-729, and my amp is a beosystem 10 witch is a radio with build in amp.
The Denon head amp only has three options, 24dB, OFF/MM and 32 dB.

And the cartridge is?

Edit: I see the turntable came with a Philips 401 cartridge originally. If that's the one you're using, you're attempting to use an MM cartridge with and MC step-up. The HA-500 is designed for cartridges with much lower output than your MM cartridge, so you are indeed experiencing the effects of much too much gain.

What you actually need is an MM or MM+MC phono stage, as your Beosystem 10 likely only has line inputs.

The Beosystem 10 has no phono stage,the Denon HA-500 is to boost MC to MM level - not a phono amp.
You need a phono amp

I am looking to buy a Denon PMA-710 amp, do you then think it will work properly?
(Its the vintage PMA-710 model, not the newer PMA-710AE)

From what I see here
https://www.whathifi.com/denon/pma-710/review
It has a MM phono stage so your Philips 401 should work into it.
